about two images of adjustment left and right and two images of front and back
If consider two images of process left and right and two images of front and back, method of adjustment can also comprise the following steps: image raw data is converted to one the 3rd image data, wherein the 3rd image data has the matrix of M*N pixel equally, the pixel that 3rd image data meta is set to the i-th row and jth row is expressed as P3 (i, j, Z1), i, j are integer, 1 i M, and 1 j N, Z1 is expressed as the first state; And analysis position is all the pixel P2 (i, j, Z2) of the i-th row and jth row and pixel P3 (i, j, Z1) presentation content, if pixel P2 (i, j, Z2) and pixel P3 (i, j, Z1) when both data differences are less than critical value, then by pixel P3 (i, j, Z1) P3 (i is revised as, j, Z3), and by analysis with adjustment after the 3rd image data there is the third state.
about the critical value model of pixel P2 (i, j, Z2) with pixel P3 (i, j, Z1) both data differences enclose
Analyze pixel P2 (i, j, Z2) with the step of pixel P3 (i, j, Z1), if occur, the data difference that following situation can be considered as both is identical: (1) is less than 10 gray scale unit when the gray scale variation value of two pixels; (2) when the brightness change of two pixels is less than 5 brills; (3) when the value of chromatism of two pixels is less than 1 value of chromatism unit.Note that present embodiment is only used for, when presenting a demonstration, also to set merely wherein a kind of situation, or two kinds of situations wherein, or the limited field of gray scale variation value, brightness changing value or value of chromatism is changed according to design requirement, but not as limit.
Referring again to Fig. 6.In this embodiment, diagram numbering 620,640,660 is the image data through left and right adjustment, and icon numbering 630,650 is the image data through front and back adjustment.Two images of left and right and two images of front and back are adjusted owing to considering, first image data, the second image data can be respectively left-eye view, the right-eye view in same a series of paintings face, and the 3rd image data is the left-eye view in next a series of paintings face, now, analyze pixel P1 (i, j, Z1) with pixel P2 (i, j, Z2) way be equivalent to two images adjusting left and right, and analyze pixel P2 (i, j, Z2) be equivalent to the way of pixel P3 (i, j, Z1) two images adjusting front and back.
Similarly, the first image data, the second image data can be respectively right-eye view, the left-eye view in same a series of paintings face, and the 3rd image data is the right-eye view in next a series of paintings face, therefore pixel P1 (i is analyzed, j, Z1) and pixel P2 (i, j, Z2) way can produce two image effects on the right left side of adjustment, and analyze pixel P2 (i, j, Z2) and pixel P3 (i, j, Z1) way can produce adjustment before and after two image effects.
about the adjustment mode of other change
In method of adjustment based on pixel, except the gray scale variation value of the constant person of GTG, two pixels be less than 10 rank within (being such as 6 rank), also the gray scale variation total value within the scope of three picture frames can be less than 10 rank, pixel is set to the third state.Therefore, such as utilize image changing value itself or all can determine the third state to the calculation being less than three images change image quality.
For 3D info class adjustment can by specific degree of depth algorithm or in advance relative method change out the 3D image with first ~ third state.
Depth information method: in plane, the region of certain depth value is defined by the third state, all the other are sequentially the first state and the second state.Or particular range (degree of depth rank are less than 10 rank).
Relative method in advance: the difference that each point image loads before and after depth data is compared.(such as, grey decision-making is within 10 rank units within limits for image changing value; Brightness value is less than 5 brills; Value of chromatism is less than 1 value of chromatism unit), all can enter the third state.Detailed way can refer to Fig. 2, about the similarities and differences analyzer of 3D image class.
The similarities and differences analyzer of 3D info class or the degree of depth are turned to the transformation approach of the converter (depth-to-statetransfer) of state, depth information method (depth data method) and relative method (pre-load pixel comparison) in advance can be taked.Wherein depth information method is according to 2D image data and depth data, produces the depth data with the third state relatively.Relative method is according to 2D image data and depth data in advance, produces the left image data (the first image data) and right image data (the second image data) with the third state.
about the Graphics Processing mode of the third state in 3D
Different 3D displays and display technique can be corresponded to by analysis from the image data after adjustment.The pixel content of each image data may with the first state, the second state or the third state.The way of output can have two kinds of practices, is respectively predefine method and direct analysis.
The content of this pixel and state representation can be Pixel (R, G, B, StateX), state StateX=1 wherein or 2 or 3 by predefine method: when a certain pixel is expressed as Pixel (R, G, B).
Direct analysis: Block (N)=StateX, state StateX=1 wherein or 2 or 3, and the pixel Pixel after adjustment " (R, G, B).The pixel group of multiple locus can form a block (block), so can first take predefine method to be adjusted by multiple Pixel (R, G, B, StateX) within a block, then carries out converted.The decision of overall Block status can by the average of each pixel in block or the analysis by space and ratio, calculates corresponding pixel status in the picture frame of the analysis mode that also can be similar to similarities and differences analyzer time forwards, backwards.
With by analysis with adjustment after image data can be applied to polarisation 3D and naked technology of looking 3D.Consider that the control of polarisation polarity may be one with the block of multiple pixel and control unit, although a block has multiple pixel, wherein a kind of pixel status only can be selected to control.Fig. 7 ~ Fig. 9 converts according to three kinds of blocks of embodiments of the invention the schematic diagram that state controls to.Be expressed as the first to the third state of different pixels with numeral 1 to 3 in Fig. 7 ~ Fig. 9.
